动物的集体行为产生了各种各样的空间模式，如群居昆虫的巢穴。这些结构是由个体遵循一套简单的规则建造的，在物种内部和物种之间略有不同，以产生大量的形状多样性。然而，很少有人知道的起源和进化的行为机制调节巢结构。在这项研究中，我们讨论了推断模式形成背后的集体行为的进化使用系统发育框架的角度。我们回顾的集体行为，可以描述由一组行为规则，并为环境和行为参数值的变化产生不同的模式。我们认为，这种机制可能是在相关物种之间观察到的模式多样性的起源，并且，当它们被放置在适当的条件下，物种有行为的潜力，形成在相关物种中观察到的模式。低等白蚁建造庇护管的比较分析与这一假设是一致的。虽然在自然条件下使用的避难所管是不同的物种，大多数现代物种有潜力建立它们，这表明避难所管建设的行为规则进化一次在现代白蚁的共同祖先。我们的研究强调，行为规则的比较研究有可能揭示集体行为的演变。
Animal collective behaviors give rise to various spatial patterns, such as the nests of social insects. These structures are built by individuals following a simple set of rules, slightly varying within and among species, to produce a large diversity of shapes. However, little is known about the origin and evolution of the behavioral mechanisms regulating nest structures. In this study, we discuss the perspective of inferring the evolution of collective behaviors behind pattern formations using a phylogenetic framework. We review the collective behaviors that can be described by a single set of behavioral rules, and for which variations of the environmental and behavioral parameter values produce diverse patterns. We propose that this mechanism could be at the origin of the pattern diversity observed among related species, and that, when they are placed in the proper conditions, species have the behavioral potential to form patterns observed in related species. The comparative analysis of shelter tube construction by lower termites is consistent with this hypothesis. Although the use of shelter tubes in natural conditions is variable among species, most modern species have the potential to build them, suggesting that the behavioral rules for shelter tube construction evolved once in the common ancestor of modern termites. Our study emphasizes that comparative studies of behavioral rules have the potential to shed light on the evolution of collective behaviors.
